gptarget to extract dispersion curve from a file.target

When I used the command line to run the codes as following:
Code: Select all
gptarget E -disp 0 Lep_ring01_3C.target
Code: Select all
gptarget E -disp 0 Lep_ring01_3C_dinver.target
to extract the dispersion curve of fundamental Rayleigh from the below two files,
a message "gptarget: curve index out of bounds (-1)" is shown.
What's the problem? And I use the Geopsy.org packages, release 2.4.4, win32.
Waiting for your response. Thank you very much!

You target files do not contain any dispersion curve. Open them inside dinver to check.
They contains only SPAC curves. Currently gptarget has no option to extract autocorrelation curves. As stated in the help message, this can be implemented upon request. I'll add this task to my schedule.

Many Thanks，Admin. I have noticed that. I had made a mistake that I thought using gptarget can obtain a dispersion curve from the autocorrelation curves by some kind of calculation. Is there any plugin to do this in your progarm? Thanks!

spac2disp is the dedicated tool for that. More information about the dispersion curve retrieval from autocorrelation curves can be found in
Wathelet et al. 2005.
